Description
Technical field
The invention belongs to garden equipment technical field of tools, it is related to a kind of adjustable cutter for mower and its adjusting method.
Background technique
Existing cutterhead is mounted on grass trimmer, using motor high speed rotation, to be mowed using the sawtooth at cutterhead edge, once
Sawtooth on cutterhead encounters hard object, and the sawtooth on cutterhead may will disconnect, and needs to dismantle and replace with new cutterhead at this time, so that
Whole efficiency is lower, and even if replacing with new cutterhead, is also easy to be broken by hard object；
It is existing application No. is 201710091072.5, entitled " a kind of Combined type grass cutting rounding machine cutter and its installation and removal
The Chinese invention patent application of method " combines using disc operator disk and circular ring shape pair cutterhead and to form Combined type grass cutting machine
Cutter can choose using operator disk or secondary cutterhead, to adapt to a variety of environment when in use.But it has the following problems:
1, adjusting method is that secondary cutterhead is dismounted on operator disk, is more troublesome, and sequentially pass through connecting hole using fastener
One, connecting hole two and connecting hole three need to mount and dismount fastener one by one, therefore dismounting is more troublesome, and must assure that simultaneously
Connecting hole one, connecting hole two and the alignment of connecting hole three could install, therefore accuracy requirement is higher；
2, operator dish external diameter is different with secondary cutterhead outer diameter, while the operate blade on disk and operator disk axis distance and secondary knife
Cutting teeth on disk is different from axial line distance on secondary cutterhead, therefore disk of operating is different with secondary cutterhead cut coverage, can make to using
At influence；It is therefore desirable to improve.
Summary of the invention
The purpose of the present invention is be directed to the above-mentioned problems in the prior art, provide it is a kind of adjust it is more convenient, together
When have a variety of work structuring available, and will not be to using the adjustable cutter for mower impacted and its adjusting side
